Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a liquid detergent composition used as shampoo, etc. More specifically, it is a liquid detergent composition that has fine creamy foam quality and excellent 7B foam durability. relating to things.

Problems to be Solved by Conventional Technologies and Inventions In recent years, there has been a demand for detergents for hair, body, etc. that not only foam during cleaning, but also have a creamy feeling and long-lasting foam. .

In particular, when it comes to hair cleansers such as shampoos, especially when women wash their hair, it takes a considerable amount of time to wash the hair, depending on the length of the hair. If the properties are insufficient, problems such as a decrease in the feeling of use and tangled hair may occur.Therefore, foaming feeling and foam sustainability are important characteristics for cleaning products. .

However, although a variety of conventional cleaning agents have been developed that have excellent foaming properties, the creamy feel of the foam and the sustainability of the foam are still not satisfactory.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a liquid detergent composition that has both fine and creamy foam quality and excellent foam persistence.

Means and Action for Solving the Problems As a result of intensive research to achieve the above object, the present inventors used sulfosuccinic acid monoester as an anionic surfactant, and further used a silicone derivative in combination with this. As a result, the two work synergistically to create a fine, creamy, slippery foam, excellent foam retention, rich foaming, and a moist, smooth finish that is not sticky at the time of finishing. It was discovered that a liquid cleaning composition can be obtained, and the present invention was completed.

Therefore, the present invention provides a liquid cleaning composition comprising a combination of a sulfosuccinic acid monoester and a silicone derivative.

The present invention will be explained in more detail below.

As the sulfosuccinic acid monoester used in the present invention,
Although there are no particular limitations, the alkyl sulfosuccinic acid monoester or alkyl ether sulfosuccinic acid monoester represented by the following general formula (1), the alkanolamide sulfosuccinic acid monoester or the alkanolamide ether sulfosuccinic acid monoester represented by the following general formula (■) One or more esters are preferably used.

General formula (1) General formula (n) (However, in the formula, R4 is an alkyl group having an average of 9 to 15 carbon atoms, R2 is a hydrogen atom or a methyl group, AO is an oxyalkylene group having 2 to 3 carbon atoms, n is an integer from O to 20, and M

The alkyl group of ~15 may be linear or branched, and examples include lutononyl, decyl, 7-decyl, dodecyl,
Examples include tridecyl, tetradecyl, and pentadecyl. It should be noted that there is no problem even if an alkyl group outside the range of 9 to 15 carbon atoms is included, as long as the average carbon number of the alkyl group in the mixture of compounds having alkyl groups of various carbon numbers is 9 to 15 as a whole. By setting the average number of carbon atoms in the alkyl group within this range, good foaming power can be imparted. On the other hand, when the average carbon number of R4 is 8 or less or 16 or more, the foaming power of the liquid cleaning composition may become insufficient.

As described above, Ml and M2 are selected from hydrogen atoms, alkali metal ions, ammonium ions, and hydroxyammonium ions, but M and M2 may be the same or different. Here, examples of the alkali metal include lithium, sodium, potassium, etc., and examples of the hydroxyalkylammonium include monoethanol ammonium, noethanol ammonium, triethanol ammonium, methyldieta/-JL/ammonium, etc. .

The compatibility of the system of the present composition can be improved by further incorporating a lower alcohol such as ethyl alcohol or isopropyl alcohol within a range that does not adversely affect foaming.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention provides a composition in which a sulfosuccinic acid monoester and a silicone derivative are used in combination.

Although the mechanism by which the composition of the present invention exerts such excellent effects is not clear, it is likely that the sulfosuccinic acid monoester and the silicone derivative interact to stably arrange the foam film. This is thought to be because it improves the viscoelasticity of the foam film and slows down the drainage rate.

Next, the present invention will be explained in more detail based on the following examples, but the present invention is not limited to these examples. Before explaining each side, the evaluation method and evaluation criteria adopted by each side will be explained.

Creamy feeling of foam After hair was divided into 2 ft., a standard sample and a test sample of 3I were applied to the left and right sides respectively, and lathered, the creamy feeling of the foam was subjected to a sensory test using the Shini point comparison method by 20 testers. The results were evaluated and evaluated using statistical processing.

The standard sample is polyoxyethylene alkyl ether sulfate) IJum (average number of moles of EO added =
15 aqueous solution (shown as a standard product in Table 1) of 3. alkyl group: C12/C1, = 1/l) was used.

Evaluation criteria ○: 5 points are significant, and the test sample is more favorable.

△: No significant difference.

×: Significant by 5 degrees, and the standard sample is preferable.

20 m of a 6% aqueous solution of a long-lasting foam cleaning composition (25°C) was added to 100 m/
0.2g of liquid lanolin was added as artificial dirt to this, and it was shaken 20 times for 10 seconds.
The foam volume <rrtt> was measured after 10 minutes and after 10 minutes, and the rate of change of both was determined from the following equation, and the sustainability of the foam was evaluated and judged according to the following M5 standard.

Evaluation criteria: ○: 125 units or more △: 110 to less than 125 units × less than 110 units [Examples 1 to 13. Comparative Examples 1 and 2 Cleaning compositions having the formulations shown in Table 1 were prepared, and the creamy feel of the foam and the persistence of the foam during use were evaluated according to the evaluation method described above.

The above evaluation results are also listed in Table 1.

As is clear from the results in Table 1, the cleaning compositions of Examples 1 to 13 were better in terms of both the creaminess of the foam and the durability of the foam than the standard cleaning compositions. On the other hand, the cleaning compositions of Comparative Examples 1 and 2, which did not contain either sulfosuccinic acid monoester or silicone spinner, were both found to be effective in improving the creaminess of the foam and the persistence of the foam. There wasn't.

[Examples 14 to 16] Three types of cleaning compositions were prepared according to the formulations assigned in Table 2, and foam glue I was prepared in the same manner as in Examples 1 to 13.
) -Evaluation was made on the squishy feeling and the persistence of foam.

The above evaluation results are also listed in Table 2.

Table 2 As is clear from the results in Table 2, even when the cleaning composition of the present invention is blended with other ingredients such as fragrances and pigments, it is not affected by these ingredients and is superior to standard cleaning agents. Compared to the composition, both the creamy feeling of the foam and the persistence of the foam were good.
